A first injection port 500 for injecting air is coupled to the first body 100 and a second injection port 600 for injecting a chemical solution is coupled to the second body 200.

The needle body 800 is coupled to the first body 100, the second body 200, and the third body 300, which are integrally coupled to each other.

The forward and backward movement of the needle member 800 is exerted by the propulsive force due to the air injection and the elastic force of the spring 820 in contrast thereto.

A needle 810 is formed at the tip of the needle member 800 and a needle 810 is inserted into the first body 100 and a nozzle hole 110 through which the chemical solution and air are discharged is formed.

Therefore, when the needle member 800 is moved forward and backward, the needle 810 operates to protrude and retract the nozzle hole 110 a plurality of times, thereby removing the foreign matter, so that the cleaning operation can be performed.

Each component will be described in more detail as follows.

The first body 100 has a nozzle hole 110 formed at a front end thereof and has a plurality of protrusions 120 protruding from both sides of the nozzle hole 110 and having pores 122 facing each other, A passage 101 communicating with the opening is formed on the inner side, and a fitting hole 102 through which the first injection port 500 is coupled is formed on the side surface.

Each of the plurality of protrusions 120 has an inclined surface 121 toward the nozzle hole 110 and pores 122 are formed in the inclined surface 121. Each of the pores 122 is formed symmetrically with respect to each other, So that the chemical liquid injected through the nozzle hole 110 is finely pulverized and atomized into fine particles.

The first injection port 500 is coupled to one side of the first body 100 to supply air to the internal passage 101.

The second body 200 is coupled to the opening and the passage 101 of the first body 100 and has a tubular tip 210 protruded to be coupled to the nozzle hole 110 at one side, And a passageway 201 communicating with the coupling part 230 is formed in the inside of the coupling part 230.

The second inlet (600) is coupled to one side of the second body (200) to supply the chemical liquid to the internal passage (201).

When backwashing is performed to remove foreign substances such as chemical solution residues remaining in the internal passages 201 of the first body 100 to the third body 300, Or washing water may be supplied.

A valve coupling hole 220 is formed in the second body 200 at a position opposite to the second injection port 600 and the water drainage member 700 is coupled to the valve coupling hole 220.

An outlet 702 is formed on the other side of the water discharging member 700 and a steel ball 720 that blocks the inlet 701 and the steel ball 720 are connected to the valve connecting hole 220, And a spring 710 elastically supporting the steel ball 710. The steel ball 720 is opened by the pressure applied from the inlet side so that the fluid can be transferred to the outlet 702. [

7, when air or clean washing water is injected into the second injection port 600 at a high pressure, the interior of the second body 200, the first body 100, and the third body 300 is cleaned The steel ball 720 is opened by the pressure of the air or the washing water and the backwashing which is discharged to the outside through the outlet 702 of the water discharging member 700 can be performed.

The third body 300 is coupled to the coupling part 230 of the second body 200 and has a predetermined length to be coupled to the second body 200 and the first body 100 at one side thereof. A plurality of bolts 310 are horizontally formed, a passage 301 is formed therein, and a rear wall 390 is formed at the rear.

A through hole 391 is formed at the center of the rear wall 390 so that the rear end of the needle member 800 is penetrated and exposed.

The needle member 800 is coupled through the first body 100, the second body 200 and the third body 300. The tip member 210 of the second body 200 penetrates the tip of the second body 200 A needle 810 is inserted into the nozzle hole 110 of the first body 100 and a spring 820 is coupled to the rear end of the needle body to be elastically supported at the rear end of the third body 300.

6, the air is injected into the first injection port 500, the chemical liquid is injected into the second injection port 600, and the mixture of the air and the chemical liquid is injected into the nozzle holes 110 and the pores And a part of the air pressure is transferred to the third body 300 through the bypass unit and then the flange 840 of the needle member 800 is pressed with a weak force so that the needle member 800 is retracted So that the needle 810 opens the nozzle hole 110.

The air and the chemical liquid can be injected through the nozzle hole 110 and the pores 122. [

Meanwhile, air supplied to the first body 100 is transferred to the third body 300 so that a part of the air injected through the first injection port 500 can be exerted as an urging force to reverse the needle member 800 Bypass section is included.

The bypass unit includes a first bypass passage 910 connected to the passage 101 of the first body 100, a second bypass passage 920 passing through the second body 200, And a third bypass passage (930) connected to the passage (301) of the body (300).

The first bypass passage 910 is formed to be inclined downward toward the second body 200. The second bypass passage 920 is connected to the first bypass passage 910 and is formed substantially horizontally, The third bypass passage 930 is connected to the second bypass passage 920 and is formed to be upward sloped.

The outlet 702 of the third bypass passage 930 is formed in the inner passage 301 of the third body 300 and is inclined upward toward the flange 840 of the needle member 800.

4, when the high-pressure air is injected through the first injection port 500 in the state where injection of the chemical solution is stopped, most of the air flows through the first bypass passage 910 to the third bypass passage 930 so that the needle member 800 is retracted by pressing the flange 840.

When the injection of air is stopped, the needle member 800 advances due to the elastic restoring force of the spring 820. [

In this way, the forward and backward movement of the needle member 800 is repeated several times so that the nozzle hole 110 can be cleaned by the needle 810.

An annular flange 840 is formed on the outer circumference of the needle member 800 to be in contact with the inner passage 301 of the third body 300. One end of the spring 820 is supported by the flange 840, The front and rear ends of the third body 300 are coupled to be supported by the rear wall 390 of the third body 300 so that the forward and backward movements can be performed in a resilient manner such that the needle 810 can clean the nozzle hole 110 do.

On the other hand, a manual operation means for manually advancing and retracting the needle member 800 is included.

The manual operation means includes an adjusting member 380 which is in close contact with a rear end of a third body 300 having a screw coupling hole 382 formed at the center thereof so as to be screwed to the rear end of the needle member 800.

Therefore, when the adjusting member 380 is rotated clockwise or counterclockwise, the threaded needle member 800 is moved forward or backward to perform cleaning of the nozzle hole 110.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
